well the thing is....enhancements are not specific to digital....
when i started off shooting film, the lab did the compensation and all for me....
and now tt i am into alittle of darkroom myself, u will be surprised at the amt of dodging and burning ppl do there...
u see....its a trend, some puristist may argue about getting the best results from say, slides. but even projectors have different light bulbs and all tt will give u different results etc....
so to say, people have been doing enhancements all along...its a natural progression from learning how to shoot....then trying to make ya shots have more "impact" on presentation .... the digital workflow is just such a device...
truth be to tell....most stuff we see on photoshop are mere extensions of the darkroom...juz tt the darkroom is now inside ya cpu....take perspective correction, it could be achieved in the darkroom my tilting ya printing board when exposing the film onto the print...USM is done by overlaying two pieces of film...
so my stand is clear.... it is not specific to digital at all.... instead, its a natural progression....
he nxt stage would be that people will notice that ...shooting correctly then bringing it to post production to enhance it further ...will be alot better than shooting wrongly then trying to salvage the print.... this is my prediction, and also my personal experience
juz my 2 cts...
cheers...
